Single-Marker Hydraulics
Refer to Figure 7.
1. Attach the 90-degree swivel elbow (1)
to the rod end of the marker cylinder
(2). Insert the orfice (3) in the base
end of the marker cylinder (2). Attach
the 90-degree swivel elbow (1) to the
base end of the marker cylinder (2).
2. Uncoil and attach hose (4) 288" to the
swivel elbow at the rod end of the
marker cylinder (2). Uncoil and attach
hose (5) 252" to the swivel elbow (1) at
the base end of the marker cylinder
(2).
3. Assemble the elbow fittings (7) to the
end of the hoses (4) 288" and (5) 252".
Route hoses through the frame mem-
ber cut-outs and hose clamps parallel
to the hoses feeding the outer gauge-
wheel cylinder. Route the hoses (8)
348" down the center of the tongue
tube and connect them to the elbow
fittings (7).
IMPORTANT: JIC fittings do not re-
quire high torque. JIC and O-ring fit-
tings do not require sealant. To
avoid cracking fittings or castings
from overtightening, do not use
plastic sealant tape.

Refer to Figure 8.
4. Fine tune the hose placement. Make a loop in both hoses
near the folding hinge..This loop should be large enough to
allow the outer wing to flex without the hoses pulling tight.
Maintain the loops by clamping the hoses in the center hole
of the existing hose clamps. Use the split rubber sleeves as
bushings between the clamps and the marker hose. Use the
cable ties (6) supplied with the kit to hold the hoses away
from any pinch point. Check to be sure hoses do not rub on
tires when folded in transport. This can happen if too much
slack is provided.
IMPORTANT: Read and complete Setup Adjustments,
page 6 before folding the markers.
